The extent of control was limited to the coastline and political interference was minimal.
Another important factor driving old imperialism was religious missionization. The Portuguese and Spanish were fervent Roman Catholics, eager to spread their faith to the indigenous natives. Hence in the old imperialism era, the Christian missionaries went first into unknown lands to spread their faith, followed by traders and soldiers to protect them. These groups also played an important role by discovering new lands, assessing its potential and encouraging their respective governments to imperialize and trade in these areas. .
New imperialism Its differences and advantages over old imperialism.
New imperialism marks the era of unprecedented global expansion of European countries after the Industrial revolution during the mid-to late nineteenth century. Some of the factors that supported new imperialism are the demands created by the Industrial Revolution, the improvement in transport and communication, the spread of extreme nationalism, and the civilizing mission.1 European nation-states had become very powerful at this point because of industrialization and because of the organizational efficiency of the government, which distinguishes the new from the old imperialism whereby corruption was more prevalent. During this new imperialism period, imperialists took on political control of their colonies and established colonial governments which had the advantage of drawing upon the entire imperial nation's strength and wealth for governance. Gradually, corporate enterprises which had the disadvantage of having to keep making profits to gain investor's confidence vanished due to the high levels of corruption within the companies and limited company resources. .
With the advent of the Industrial Revolution, the great powers of the world were motivated to dominate smaller countries by the need to expand their economies, to acquire raw materials and additional sources of labor, or to find outlets for surplus capital and markets for surplus goods.
